　　New research has shown that you might not just be feeling blue, you may also be seeing it differently. A blue mood may be more than just a figure of speech. Your mood may also affect how you see the world around you, according to a new study. A team of researchers has demonstrated that sadness could have an effect on the way we see colors.

　　The team, led by psychology researcher Christopher Thorstenson of the University of Rochester, found that people in whom they had induced a sad mood were less accurate in identifying colors on the blue-yellow axis(轴线), compared to people who weren’t feeling sad.

　　“We were already deeply familiar with how often people use color terms to describe common phenomena, like mood. even when these concepts seem unrelated,” Thorstenson said in a statement. “We thought that maybe a reason these metaphors emerge was because there really was a connection between mood and identifying colors in a different way.”

　　Thorstenson and his team are not the first to identify a link between a depressed mood and a difference in recognition. In 2010, Emanuel Bubl and his team at Albert Ludwigs University Freiburg in Germany first demonstrated a link between decreased contrast sensitivity and depression. This was supported by a 2013 paper by Johnson Faro et al of the University of Singapore.

　　The team conducted two studies．In the first, 127 participants were chosen randomly to watch one of two video clips, which had been proved in previous studies to feel either sadness (a cartoon clip) or amusement (a stand-up comedy routine). They didn’t do that in a specific order.

　　The entire group was then tasked with identifying the colors in 48 continued color swatches. The group that had been shown the cartoon clip was measurably worse at identifying colors along the blue-yellow axis, although no difference was found along the red-green axis.

　　For the second study, 130 participants were randomly assigned to watch either a sad clip or a neutral one. The sadness group showed reduced ability to identify colors along the blue-yellow axis than the neutral group. Again, there was no difference along the red-green axis.

　　Because of this lack of difference along the red-green axis, the researchers say the difference in ability cannot be explained by lack of effort, or focus. If the subjects were badly focused, they would have performed equally badly along both color axes.
